How to use Change GIF Speed
- Choose the source file or ordered images.
- Review animation-specific controls.
- Preview and download the measured result.
Change GIF Speed
Speed up or slow down an animated GIF online by changing frame delays without dropping frames.

Change GIF Speed uses a separate frame-aware pipeline; it never sends an animated file through the static first-frame canvas path.
How OpenFileTools processes it
Local processing, explicit choices.
The browser lazy-loads GIF decoding and encoding code, composites disposal-aware frames, applies the operation to every frame, and creates an animated GIF locally.
Quick technical summary
What this tool changes.
| Property | Behavior |
|---|---|
| Processing | Browser only; no image upload |
| Original | Never changed |
| Frames | Preserved |
| Timing | All delays scaled and safely clamped |
| Custom speed | 0.05× to 20× |
Speed up or slow down a GIF without dropping frames
The speed control scales every frame delay while retaining frame order and count. A 2× speed makes the animation roughly twice as fast by shortening delays; a 0.5× speed makes it roughly twice as slow by lengthening them.
- Preset and custom speeds are available.
- Custom speed accepts 0.05× through 20×.
- Very short delays are clamped to a minimum reliable GIF delay.
Compare the old and new animation duration
The tool reports original duration and new duration before the final download so the timing change is explicit. It does not silently remove frames or reduce the frame rate as a compression shortcut.
Questions, answered.
How do I speed up a GIF?
Choose a value above 1×, preview the new duration, and process the GIF. Frame count stays the same.
How do I slow down a GIF?
Choose a value below 1×. The tool lengthens frame delays instead of duplicating frames.
Does changing GIF speed remove frames?
No. Current speed changes preserve frame order and count.
